Washington Times columnist Jeffrey Kuhner called for President Obama's impeachment over the Boston Marathon bombings, accusing the president of being "unwilling" to keep Americans safe.

In his April 26 Washington Times column, Kuhner wrote that Obama "has been unable -- even unwilling -- to keep us safe" from terror attacks, including the bombings in Boston, because "[h]e refuses to acknowledge that we are in a war with radical Islam." Kuhner added: "It's time he is held responsible for his gross negligence. It's time that he be impeached. Justice demands no less."

Kuhner's call to impeach the president comes a week after Fox News host Brian Kilmeade blamed Obama's Middle East policy for the bombings.

From Kuhner's column:

Under Mr. Obama's watch, Islamic terrorists have targeted the United States repeatedly -- the underwear bomber, the Fort Hood shooting, the killing of an Army recruiter in Arkansas, the consulate in Benghazi and now Boston. The president has been unable -- even unwilling -- to keep us safe. The reason is simple: He refuses to acknowledge that we are in a war with radical Islam. The Boston bombings were not the acts of criminals. They were an act of war against Americans. The commander in chief has the duty to not only defend America, but to identity and denounce the enemy. In short, he must fight back.

The Boston massacre was a defining moment. It exposed Mr. Obama's narcissistic and reckless approach to combating terror. There can be no illusions any longer -- we are in a clash of civilizations between radical Islam and the West. Mr. Obama has denied this painful reality long enough. By burying his head in the ideological sands, he has made Americans pay a terrible price. It's time he is held responsible for his gross negligence. It's time that he be impeached. Justice demands no less.

Kuhner has repeatedly pushed for Obama's impeachment. In March 2011, Kuhner argued that Obama should be impeached over his handling of the military intervention in Libya, and in March 2010, Kuhner called for Obama to be impeached if he signed a health care reform bill passed via a legislative procedure known as a "self-executing rule."
